Subject: [PATCH] Add alias for `amd64` to `x86_64`
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`amd64` gets returned by `repository_ctx.os.arch`, and yet the CPU constraint only has `x86_64`. This becomes un-ergonomic when trying to set up repository and toolchain rules—I constantly have to ask myself which is which/try it out. `arm64` has an alias to `aarch64`, so there is precedent for including an equivalent name when the implementation-canonical name may not be as friendly or widely known.
